pub fn irfft(input: &Array1<Complex64>) -> Array1<f64>Expand description
Compute the inverse real FFT producing a real-valued array.
ยงExamples
use ndarray::Array1;
use num_complex::Complex64;
let spec = Array1::from_vec(vec![Complex64::new(1.0,0.0); 3]);
let x = scir_fft::irfft(&spec);
assert!(x.len() >= 2);
